MacSlow: I think this is a similar but different problem because first up your examples are H264 whereas mine where MPEG-4 video.
Secondly my examples played in xine but not gstreamer whereas yours seem to stutter and make a strange cricketty sound in xine even though there is a fair amount of CPU left. -- totem-gstreamer doesn't play Apple QuickTime movie (fast start) https://launchpad.net/bugs/3236 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
